There are **3** points possible in Iteration 1:
1. Artist Creation (must include all attributes)
2. Photograph Creation (must include all attributes)
3. Artist #age_at_death
Use TDD to create a Photograph
and an Artist
class that respond to the following interaction pattern.
For age_at_death
, assume an artist was born and died on the same day.
pry(main)> require './lib/photograph'
#=> true
pry(main)> require './lib/artist'
#=> true
pry(main)> attributes = {
id: "1",
name: "Rue Mouffetard, Paris (Boy with Bottles)",
artist_id: "4",
year: "1954"
}
pry(main)> photograph = Photograph.new(attributes)
#=> #<Photograph:0x00007fc2d1050c80...>
pry(main)> photograph.id
#=> "1"
pry(main)> photograph.name
#=> "Rue Mouffetard, Paris (Boy with Bottles)"

There are **3** points possible in Iteration 2:
4. Curator Creation (must include all attributes)
5. Curator #add_photograph & Curator #add_artist

There are **3** points possible in Iteration 2:
7. Curator #photographs_by_artist
8. Curator #artists_with_multiple_photographs
9. Curator #photographs_taken_by_artist_from
Use TDD to update your Curator
class so that is supports the following methods:
photographs_by_artist
- This method will return a hash with artists as keys, and an array of their photographs as values.artists_with_multiple_photographs
- This method returns an Array of names of artists who have more than one photographphotographs_taken_by_artists_from(string)
- This method takes a String representing a country. It returns an Array ofPhotograph
s that were taken by a photographer from that country.
The Curator
class should now respond to the following interaction pattern:

# => true

There are **3** points possible in Iteration 2:
10. Curator #load_photographs && #load_artists
11. Curator #photographs_taken_between
12. Curator #artists_photographs_by_age
Use TDD to add the following methods to your Curator
class:
load_photographs(file)
- This method takes a path to a CSV file containing photographs and adds them to theCurator
. You may find the includedFileIO
class useful.load_artists(file)
- This method takes a path to a CSV file containing artists and adds them to theCurator
. You may find the includedFileIO
class useful.photographs_taken_between(range)
- This method takes a range and returns an array of all photographs with a year that falls in that range.artists_photographs_by_age(artist)
- This method takes anArtist
object and return a hash where the keys are the Artists age when they took a photograph, and the values are the names of the photographs.
